Answer:15x to the second power+8x+3
Step-by-step explanation:
75 and what units it is. A=L×W In this case the length was 15, and the width was 5.
I got 83 as the perimeter
Adjacent angles share a vertex and a side. For EDF, since the vertex is completely unrelated to AEB, it is not adjacent. For DEA, since it shares a vertex (the line BED, and they add up to get it) and shares the line EA, it is adjacent. For GDA, since it clearly does not share a common vertex, it is not adjacent.
